Detailed description of the invention

Now be described in exemplary absorbent hygienic article manufactured between implementation period of the present invention.For the sake of simplicity, diaper is used as an exemplary absorbent hygienic article, although will recognize as those skilled in the art, technology of the present invention can be applicable to other sanitary absorbent articles of such as incontinence garments, sanitary towel and medical dressing.

The same with many traditional sanitary absorbent articles, the health that exemplary diaper has close user is placed and the absorbent cores covered by impermeable tergite.The liquid of absorbent commodity is arrived like this or semisolid material will be absorbed by absorbent cores but will be prevented from so that can not permeates impermeable tergite further from the health of user.Such absorbent commodity controls the flowing of liquid from the health of user and semi-solid liquid effectively.Absorbent commodity also can be provided with the top flat be placed on the side contrary with impermeable tergite of absorbent cores between absorbent cores and the health of user, and described top flat is permeable and be used for keeping absorbent cores and/or making user comfortable.Being configured in like this is known in the art, and the wide in range change of the type of such article will be not described further in this, although those skilled in the art can not have any problem to the technology disclosed in the application of such article when needing.

Be intended to have conducting element be such as used for the sense wire serving as monitoring system conductor wire absorbent commodity assembling in, sense wire should extend to contact at least partly with absorbent cores, but also needs with the position of clear and definite line arrangement to such as monitoring means or terminal connector.

Refer now to Fig. 1 to Fig. 5 to describe to manufacture and there is conduction sensing element and a kind of method of absorbent commodity implemented as of the present invention first.

In FIG, impermeable tergite 1 is shown.Described impermeable tergite have the health in use deviating from user surperficial 1a and by the surperficial 1b of absorbent cores towards the health of user.In this enforcement, sensing element is arranging at least partially and ending at the conductor wire of monitoring means along absorbent cores.But in order to ensure to connect up securely and described line is neither mobile does not also contact with each other, described line is preferably tight and be restricted to the path clearly limited during manufacture process.

Therefore, in fig. 2, line 2 extends first paragraph line 2a along the surperficial 1b of tergite 1, traverses tergite 1 arrive surperficial 1a and extend second segment 2b along surperficial 1a, end at first end 2c via hole 1c.Such structure can provide simply by straight line stitching process.

In order to ensure described line be restricted to it given line and in the manufacture of described article or do not depart between the operating period, pulling force should be applied at the two port line 2 relative to first end 2c to strain at least in part in the path pulling described line and make it at it, thus when second end of online 2 is terminated at adapter or monitoring modular, eliminate lax at least part of of any residue.In order to realize this target, described line should be fixed on first end 2c before any pulling force of applying, otherwise described line likely moves.

In order to realize such fixing, as shown in Figure 3, applying binding agent 4 and arriving the part 2b of line 2 at least partially, and a part of covering surfaces 1a.In figure 3, binding agent 4 also covers line 2 from surperficial 1b through the hole 1c of tergite 1 to surperficial 1a.The advantage of this structure is the water proofing property that ensure that tergite 1.Binding agent 4 is provided on the surface of adhesive tape 3 in this enforcement, and this surface provides for supporting the substrate of binding agent 4, make to apply binding agent to line 2 and tergite 1 simple and convenient.But binding agent can apply in another form, such as, be solidified into the liquid glue of solid, such as cyanoacrylate glue.Certainly, if layer 1 is not waterproof, if or provide other watertight composition to cover the surperficial 1a of tergite 1, be not strictly required with binding agent 4 coverage hole 1c.Whether pore 1c is not covered by binding agent, and line segment 2b is fixed by binding agent 4.

In the case of figure 3, the end 2c of line 2 stretches out from binding agent 4.The part that line 2 stretches out from binding agent is more, and the probability of the unexpected short circuit between the free end 2c of online 2 and another conductor wire (if present) is higher.In addition, the moisture outside tergite 1 undesirably may be sensed by the end 2c of line 2.Correspondingly, end 2c can cut away from line 2, preferably near or just on the surface of adhesive phase 4, as shown in Figure 4.When cutting away thread end 2c from line 2, a part for mixture layer 4 and adhesive tape 3 can be removed to ensure that thread end flushes with the end of binding agent 4, although this is dispensable equally.Flush such or shortly cut in structure, described thread end is surrounded by binding agent in the whole parts except end surface.If applied pulling force to line 2 before adhesive, also the end 2 of possibility recovery line 2 is to flush with the surface of binding agent or to encase end 2c with binding agent even completely.

Subsequently, absorbent cores 5 against the surperficial 1b of tergite 1 place in case absorbent cores 5 at least partially with the contacting at least partially of the section 2a of line 2.Then in order to the permeable top flat 6 of comfortable liquid can be placed on the side of the body-facing of absorbent cores 5, equally as shown in Figure 5.But if those skilled in the art are by understanding, the setting of top flat is completely optional.

In the layout of Fig. 5, the moisture of the abundance of osmotic absorption core 5 will contact conductor wire 2, and likely form circuit with the second enough near conductor wire.Alternatively, conductor wire 2 can be formed by spaced two conducting elements and forming circuit during line described in contact with moisture.Described line partly can scribble insulating coating along a part of section 2a, such as acrylic resin or adhesive tape, so that the moisture of the live part of the only predetermined exposure of the section of extending to 2a contacts likely forming conduct electricity with the moisture in absorbent cores.The expectation that is configured in so only detects the moisture of ad-hoc location in an absorbent core or to provide each be useful especially when detecting multiple sensing element of discrete location.

Certainly, technology reader needs not be impermeable tergite by understanding layer 1, and can be the other impermeable outer plate that has and contact with surperficial 1b or the permeable or semi permeable tergite at surperficial 1b and the other absorption component arbitrarily between impermeable barrier or other layers.Such structure falls into scope of the present invention equally.Similarly, the material of absorbent cores 5 or performance are not limited, and any absorbent cores as known in the art can be used in and not limit, comprise and use natural and/or staple fibre and/or super absorbent polymer.As for conductor wire 2, it is envisioned that silver coated nylon at present, although can use other conductor wires as known in the art.

As the replacement or supplementary of the partial coating section 2a of conductor wire 2, in order to limit the region that can realize the absorbent cores 5 sensed, or be conveniently attached to can be placed on tergite 1 with the monitoring means on the side 1b that the side of absorbent cores is contrary, described line can contact with core 5 on section 2a extend after again to be worn by the second hole 1d from surperficial 1b and come through tergite 1 to surperficial 1a, extend one section of 2c with the surperficial 1a again along tergite 1.As shown in Figure 6.Really, conductor wire can be changed repeatedly from surperficial 1b like this to surperficial 1a from first end to the second end.This limit can be in the suitable two dimensional path of conductor wire 2 from absorbent cores to monitoring means useful especially.

In implementing of the present invention second, be with or without optional top flat, described core was assembled into described tergite before wiring.Then described line can penetrate described core.This is visible in the sequence of Fig. 7 to Figure 10.

In the figure 7, absorbent cores 15 is between tergite 11 and top flat 16.In fig. 8, conductor wire 12 extends one section of 12c along the surperficial 11a of tergite 11, penetrates tergite 11 to extend one section of 12a to penetrate absorbent cores 15 equally, in absorbent cores 15 and then once penetrate tergite 11 from surperficial 11b passing hole 11c to surperficial 11a at the second hole 11d.Then conductor wire 12 continues to extend one section of 12b towards end 12c.Correspondingly, because conductor wire 12 penetrates absorbent cores 15, sensor can be more responsive to the moisture existed in absorbent cores, and moisture does not need to permeate whole absorbent cores with the side of the Body contact of user before can being triggered at sensor.Conductor wire 12 pierces into the degree of depth of absorbent cores 15 and the length of line 12 in absorbent cores 15 can be selected to provide different response characteristics.Such as, pierce into absorbent cores 15 deeply from the surperficial 11b of tergite 11 so that more promptly can react the inflow of liquid from the line that the suitable near-earth of user is arranged, but may easier instantaneous moisture or perspiration being reacted equally.

In fig .9, will such as be solidified into the fluid binder of solid, the binding agent 14 of such as cyanoacrylate glue is applied to the section 12b of conductor wire 12 with covering surfaces 11a at least partially.Alternatively, as described in the previous embodiment, adhesive tape can be used.The same coverage hole 11 of binding agent 14 is to keep the water proofing property of tergite 11.

As for enforcement above, the end 12c of line 12 is cut off, and preferably flushes with binding agent 14.As noted, as shown in Figure 10, the simple especially mode realizing this cuts away binding agent together with line so that appear at the binding agent on the surperficial 11a of tergite 11 to be removed together with the end 12c of line 12.

No matter sheet 11 or the sheet 1 in even implementing first are permeable or impermeable, the second skin can be provided not move with protective wire with any line covered along the surperficial 11a layout of tergite 11, and if necessity, provide another impermeable barrier.Such structure is shown in Figure 11.

In fig. 11, absorbent cores 25 is positioned between top flat 26 and tergite 21, and line 22 is along the surperficial 21a extension of tergite 21.Line 22 penetrates tergite 21 at the second hole 21d, extends along the surperficial 21b of tergite 21 along one section of 22a, again penetrate tergite 21 and with binding agent 24 section of the being fixed on 22b be supported on adhesive tape 23 at hole 21c.Alternatively, as embodiment above, line 22 can penetrate absorbent cores 25, and described binding agent can be the fluid binder being solidified into solid.But in the embodiment in figure 11, adhesive tape 23 is double-faced adhesive tapes, the surface contrary with the surface supporting binding agent 24 of adhesive tape 23 has second layer binding agent 27.Such binding agent can be utilized for impermeable outer plate 28 and provide support, and described outer plate can be such as supatex fabric.Similarly, the Jiao Qu provided as described about Fig. 9 can be used to static line 22 and/or fix outer plate 28 on the spot.

Once one end of conductor wire be fixed in case described line at least in part along or extend in absorbent cores, described line can be routed to and be located at monitoring means on absorbent commodity or in its vicinity.The representative configuration of such a absorbent commodity is shown in Figure 12 with the form of the diaper with conductive sensor line and monitoring means.

In fig. 12, diaper 100 has belt 120 and impermeable tergite 111, and absorbent cores 115 is remained on crotch point.Electronic unit 130 is attached to the belt 120 of diaper 100, described electronic unit have be configured to once circuit in the surface being located at monitoring means or on two contacts between connect the data processing electronics just sending alarm signal, described signal can be audible or visible, such as, by buzzer or LED.Each terminal being connected to monitoring means 130 in sensing element 112a and 112b, and extend in parallel on outside until tergite 111 overlays on the part in absorbent cores 115 along impermeable tergite 111 together.Each in sensing element 112a, 112b penetrate tergite 111, along absorbent cores 115 or extend wherein, then second time run through tergite 111 to be fixed on binding agent 114 place.In use, the moisture appeared in absorbent cores 115 closes the circuit between sensing element 112a and 112b, and monitoring means 130 can be reacted with alarm signal.Certainly, when receiving suitable transducing signal, monitoring means may have other actions, and can be initiated to the data transmission of remote sensing station, or event data can be recorded in memory, its be provided to monitoring means for post analysis.

The layout of Figure 12 is exemplary purely, and the structure of equivalence can be provided by any above-mentioned enforcement or its amendment, considers what the knowledge of himself and specific designing requirement can be expected as those skilled in the art.

Especially, in some cases, described conductor wire can be set as and be attached to adapter framework or terminal block, or can be intended to first be attached to absorbent commodity at the second end before described line extends or is fixed on first end.In this case, preferably described line extends to first end (sense terminals) from the second end (connector end), then, when the second end to be fixed relative to absorbent commodity or to remain in fixed position, pulling force can be applied at first end.In this case, the point separated in described end near first end is fixed described line and advantageously leave between fixing point and first end and be enough to crawled length, during fixation procedure, described line applied whereby and keep pulling force.

In addition, any above-mentioned feature can in conjunction with or be provided separately, and in order to similar or different technique effects, unrestrictedly can apply in other are implemented from an element implemented, intelligible as those skilled in the art.
